This year, COVID-19 broke out again in many places in China. Shanghai is one of the worst cities among them. To fight against COVID-19, Shanghai built many makeshift（临时的）hospitals in the city.
Inside a makeshift hospital, a group of 28 disinfection（消毒）robots were working busily. Each of them could work 24 hours a day without any rest.
At the same time, a group of 5G indoor multifunctional（多功能的）cloud robots were busy delivering food in the hospital. Each robot could send about 20 boxed meals at a time. They usually went to patients’ areas and waited for them to collect their food. “In the past, it usually took a worker about 20 minutes to send 20 boxed meals. Now the work can be completed in just 5 minutes with the help of these robots,” a patient said.
“The robots not only make our work much easier, but also help protect us from catching the disease（疾病）,” said a worker in the hospital.
To win the fight quickly, the local government also put more than 200 robots into use at a makeshift hospital. Outside those makeshift hospitals, more and more unmanned cars appeared on the streets to help people.

The 1.4-meter-tall robot has a giraffe-like neck, a fan on its head and a big “belly”. It can work for four to five hours at a time. The robot also uses radar（雷达）to help it find its way. With a mobile app, people can send it to different places. |  |

| Smart “Band-Aid” To learn the health condition of Olympic players and visitors, a wearable thermometer（体温计）will measure body temperatures. The thermometer is in the shape of a bandage.
